Look Who’s Stalking: 10 Creepiest Apps For Phones, Facebook, More
An odd little app for the iPhone, Situationist let you upload a photo of yourself along with a list of things you wanted a stranger to do to you in public. Situations could range from friendly ("Hug me for 5 seconds") to renegade ("Help me rouse everyone around us into revolutionary fervour and storm the nearest TV station"). In any case, it gives creepy strangers another excuse to approach people they didn’t know.
